K. s. PAPOUTSIS 210G366 HEATER Filed Oct. 1, 1936 2 Sheets-Sheet 2 Patented Nov. 30, 1937 UNITED STATES PATENT OFFEQE 1 Claim.

This relates to heaters and more especially to heating devices adapted to utilize Waste heat.

An object of the invention is to provide a simple, practical, and inexpensive device of the character described.

Another object is to provide such a device adapted to utilize the surplus heat from a stove, griddle, or the like.

Another object is to provide such a device which is readily attached to a stove or griddle without requiring any changes to be made in the structure thereof.

Other objects and advantages will appear and be brought out more fully in the following specification, reference being had to the accompanying drawings, wherein:

Fig. 1 is an elevation of a griddle embodying my invention, together with the heat storage tank and the interconnecting pipe system;

Fig.2 is a top View partly in section showing an embodiment of my invention attached thereto;

Fig. 3 is a sectional elevation of the same taken along the line 3-3 of Fig. 2; and

Fig. 4 is a similar view taken along the line 4-4 of Fig. 2.

Referring more particularly to the drawings, I show a heating element [0, which may be a burner, gas plate, or griddle, and a hot water storage tank I I, the heater Ii! being supported on a table [2 and consisting of a frame I3 having a front wall 14, side walls l5, rear wall l6, and the usual supporting legs IT. The heater is provided with a griddle or heating plate [8 supported at its corner edges by lugs I9 suitably secured to the walls l4, l5, and 16. A pipe 20 supplies gas to a manifold 2| which in turn is supported by brackets 22 to the front wall [4, the manifold having a plurality of feed lines 23, eadh of which is provided with a valve 24 having a handle 25 and connected to a mixing chamber 26 of a U-shaped burner 21 which is shown as having elongated burners or heating elements 28, there being apertures29 in the front wall l4 adapted for the reception of mixing chambers 26, the extreme ends of the burners 28 being supported by brackat 30 mounted on the rear wall I6. The burner is provided with the usual jets 3|. I show a water heating element 32 which preferably consists of a plurality of parallel tubes 33, the alternate ends of which are interconnected by return bends 34, 5 the tubes, and bends being supported by the burners 28, the tubes 32 being so arranged as to be parallel to the burners and so positioned as to lie in a vertical plane between the burners. The water inlet pipe 35 connects one end of the tube 10 system to the lower portion of tank H, and the other end of the tube system is connected to an outlet pipe 36. The usual water supply to the tank II is provided by pipe 31. The hot water supply from the tank H is provided by a pipe 15 38. Pipe 36 is connected to tank H near the top thereof.

By my novel arrangement of hot water tubes 32 the surplus heat from the burners 28 is transferred to the water from pipe 35 to the pipes 36 and the tank H, and the heat which would otherwise be wasted when the heater or griddle i0 is necessarily kept warm as it must be in restaurants is thus preserved for use as used in the form of the hot water, a generous supply of which is ordinarily required.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

The combination with a griddle having a heating element of means to utilize surplus heat thereof, said means including a plurality of spaced elongated burners and a plurality of heat absorbing tubes arranged parallel to and supported by said burners and over said spaces.
